Which two levels of protein structure principally determine the active site of an enzyme?
The primary and secondary levels of protein structure determine the active site of an enzyme. The specific arrangement of amino acids in the active site, influenced by both the primary sequence and secondary structures such as alpha helices and beta sheets, is critical for enzyme-substrate interactions.
What is the key feature of a protein or enzyme that makes its function correctly?
The most important feature that makes functional to a protein or an enzyme is its three dimensional structure based on its tertiary structure. Either, a structural protein, where alpha helices and beta sheets are vital to its function, or an enzyme, where the shape of its active site is crucial for its biological activity, the tertiary structure is the most important characteristic. In fact, the process called "protein folding" is one of the key biochemical areas of study for the scientific community.
Why does heating up a protein such as an enzyme cause it to lose function?
Heating up a protein, such as an enzyme, causes it to lose function because the increased temperature disrupts the weak bonds that maintain its three-dimensional structure. This denaturation alters the enzyme's active site, preventing it from binding to its substrate effectively. As a result, the enzyme can no longer catalyze reactions, leading to a loss of function.
What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
What are the building blocks of this biomolecule of amylase?
The building blocks of amylase are amino acids. Amylase is a protein enzyme that is composed of a specific sequence of amino acids that determine its structure and function in catalyzing the breakdown of starch into simpler sugars.
The level of protein structure primarily involved in determining enzyme activity is the?
The level of protein structure primarily involved in determining enzyme activity is the tertiary structure. This three-dimensional arrangement of the protein allows for the correct positioning of active sites and substrates, facilitating the catalytic function of the enzyme. Changes in the tertiary structure can significantly affect enzyme activity, potentially leading to loss of function.

Is renin a hormone?
by function is enzyme ... by structure is hormone
Which methods you can use to determine the primary structure of an enzyme?
Off the top of my head: techniques such as chemical and enzymatic degredation (particularly if they are targeted) coupled with various analytical techniques particularly mass spectrometry and NMR. X-ray crystallography could also be used if the enzyme can be crystallised.
Give an example of the relationship between structure and function?
One example of the relationship between structure and function is found in enzymes as their function is dependent upon its structure. Enzymes are catalytic proteins that speed up a reaction without being consumed. Their protein structure enables them to recognize their substrates, even among isomers, thus allowing them to catalyze very specific reactions. The interactions between a protein's primary structure, its amino acid sequence, determine its secondary structure of hydrogen bonded alpha and beta pleated sheets. The side chains of the amino acids help determine the next superimposed structure, the tertiary structure and the quaternary structure if the protein has one. A protein's conformation enables it to form an active site whose shape is compatible with that of the substrate. Once the substrate enters the active site, the enzyme's structure is altered as induced fit moves the active site's chemical groups into positions that enhance their ability to catalyze the chemical reaction, thus improving the enzyme's function. An enzyme's structure is so closely correlated to its function that even a slight change in a protein's primary structure can affect its conformation and ability to function. For example, although noncompetitive inhibitors bind to the enzyme away from its active site, they alter the enzyme's conformation so that the active site no longer has the right structure to bind with the substrates, preventing it from functioning correctly.

What is the protein denaturation temperature and how does it affect the structure and function of proteins?
Protein denaturation temperature is the temperature at which a protein loses its natural shape and function. When proteins are exposed to high temperatures, their structure unfolds and they lose their ability to perform their biological functions. This can lead to a loss of enzyme activity and disrupt the protein's overall function in the body.
What role does the arginine side chain play in protein structure and function?
The arginine side chain in proteins helps stabilize the structure by forming hydrogen bonds and participating in electrostatic interactions. It also plays a role in protein-protein interactions and enzyme catalysis, contributing to the overall function of the protein.

Why is protein structure important for understanding the function and behavior of biological molecules?
Understanding protein structure is crucial for comprehending the function and behavior of biological molecules because the specific arrangement of amino acids in a protein determines its shape, which in turn influences its function. Changes in protein structure can lead to alterations in function, affecting various biological processes such as enzyme activity, cell signaling, and gene expression. By studying protein structure, scientists can gain insights into how proteins interact with other molecules and how they contribute to the overall functioning of living organisms.
